Sorry, I don't see how a hidden file that says "this is unsupported" has much promotional value.

Because people asked me for it, mostly. (I'll admit it's also more pleasant for myself to use now that it's upstream, but it was a lot of work to get it upstreamed, so it wouldn't have been worth it just for that.) Now that it's there I'm trying to make it as easy to use as possible, in the hope that that entices more people giving it a try, hence this change. (And why do I bother with that? So that more people hopefully see how needlessly slow the CMake build is, so that folks trying to make the CMake build get less pushback.)
